The International Self Defense Federation (ISDF) is SOSFORALL's partner organization dedicated to teaching evidence-based self-defense techniques grounded in biomechanics, psychology, and anatomy.
Unlike traditional martial arts that require years of training or rely on physical strength, ISDF teaches practical, real-world techniques that anyone can learn—regardless of age, size, or fitness level. Our methods are designed for immediate application in dangerous situations.
ISDF training focuses on three core pillars: understanding how the human body works (biomechanics), recognizing and preventing dangerous situations (psychology), and targeting vulnerable points effectively (anatomy). This scientific approach ensures maximum effectiveness with minimum effort.
